Air emissions and emission measurements
Emission measurements ensure that companies comply with regulatory requirements for measuring, evaluation and documentation of airborne emissions, incl. odour and micro pollutants.
Emission measurements help companies comply with the requirements of the environmental approval
Air emissions are subject to regulation by the legislation and the environmental approval. The environmental approval includes requirements for set up, when it comes to exhaust, measuring and reduction of air emissions and odour. If a company does not comply with the requirements, it may risk losing the right to operate. Furthermore, measurements constitute an important parameter in corporate environmental policies.
The requirements depend on the expected environmental impact of the production.
Emission measurements at FORCE Technology are based on:
- many years of experience
- extensive knowledge
- meticulous planning
- high quality in performance.
We offer our customers advice and measurements that ensure compliance with the regulatory requirements. If the measured emissions do not comply with the limits, we can advise you on how to solve the problem.
FORCE Technology provides all-round task performance within air emissions
We ensure our customers broad-based expertise in air emissions in all stages, from prevention to documentation and reduction. We provide:
- advice on environmental legislation and -approval
- identification of requirements and challenges
- measurements and documentation
- Performance test on gas turbines, gas engines and diesel engines
- Marine/IMO measurements on marine engines
- Temperature and retention time measurements on boilers subject to regulatory processes of the Industrial Emission Directive
- Comparison of results of measurements on NOx, O2 and flow in compliance with NFS 2004:6 and the Swedish Environmental Protection Agency handbook 2004:3
- quality assurance of automated measurement systems (AMS), including QAL2, AST and QAL3
- advice of emissions reduction, including odour and NOX
- calculations with dispersion models (eg. the Danish OML-model).
We are always serious about our customer’s needs. We create measurement programs and ensure compliance with regulatory requirements by careful planning, attractive prices and delivery on time. We perform measurements and provide a report, ready for the authorities.
Our measurement technicians have at their disposal a large amount of instruments, including measuring equipment for special measurements. They get support from specialist in air pollution and from engineers throughout the organization. We work closely with our laboratory that provides chemical analysis. We are DANAK accredited in measuring and analysis within air emission and ambient air. We are also National Reference Laboratory for Air Emission Monitoring in Denmark.
Scheduling ensures quality and minimizes measurement costs
FORCE Technology always schedules emission measurements in order to meet authority conditions and requirements. We always prepare a proposal, where we specify the price and the task, in order to ensure consensus in the extent of the task and to avoid misunderstandings.
Our well-educated measurement technicians react when measurement conditions are not met. Often they can correct the situation on site in order not to repeat the measurements at a later point of time. In case of doubt, our measurement technicians will involve our team of engineers and consultants. Often we can avoid time wasting, duplication of work and expensive extra measurements.
We calibrate and service our measuring equipment at our own laboratory according to our accreditation.
Please contact our consultants, if you want to know more about air emissions or to get started with emission measurements.
Which regulations apply to my company?
Companies are regulated in different ways.
Some are subject to an environmental permit, while others are required to comply with the rules for specific sectors, and others again are subject to requirements based on individual considerations. Whatever the circumstances, they are subject to the requirement to document compliance with emission requirements and environmental impacts (compliance with ground level limit values).
Some of the regulation is laid down in EU directives, primarily the Industrial Emissions Directive, which are fully implemented in Danish legislation. Environmental permits are often drawn up on the basis of claims.
The terms of the environmental permit or any injunction will be the applicable law for the individual company.
How are odours measured?
In contrast to most chemical pollution, odours can be registered immediately, and therefore also often lead to complaints when companies emit odours. Irrespective of whether the odour is pleasant or unpleasant, it can be experienced as nuisance by neighbours.
Odours are measured by collecting air from the source, e.g. a stack, in a bag. This air is analysed within 30 hours in an olfactometer.
The analysis is performed by an odour panel comprising a minimum of four persons in our own odour laboratory. The panellists sniff to samples which are diluted less and less, until the panellists can perceive weak odour. The degree of dilution is a measure of the odour content in the bag. The panellists’ description of the odour is noted – e.g. rotten, chemical or sweet.
How odour samples are collected and analysed is described in a European standard, EN 13.725.
